Subject: [9fans] raspberry pi kernel update
Date: Wed, 6 Jun 2018 14:42:04 +0100 [thread overview]
Message-ID: <88475a1f448adbcf1ec5b9d993bb001c@hamnavoe.com> (raw)
I've made an update to the rpi 2 & 3 kernel source (armv7.s and rebootcode.s)
which fixes a couple of long-standing flaws in the multicore startup:
- dependency on the order of object files for the 5l command in the mkfile,
resulting in "lock loop" or "only 1 cpu started" error for some configurations
- flakiness in /dev/reboot, making it unreliable except with *ncpu=1
It should now be possible consistently to reboot a pi in multicore mode from
a named file using the 'reboot' or 'fshalt -r' command. This extends the
possibilities for using the Plan 9 kernel itself as a boot loader (with an rc
script as /boot/boot), eg to boot from an AoE server or over a wifi connection.
